Dear Friend I think leaving house is not a solution you need to think about your future as well as about your baby later wha will be her future. Due to your problems you'll cant spoil childs future. There is solution to every problems with little compromise problem can be solved and it can make your childs future too. Every women has a dream of her married life but shuttering it later just for a misunderstanding is wrong. Your husband wants you back home it means he loves you and want to lead his life with you and does not want to get married again this shows that he cares for you and in this he will not listen to his mother. I think you should think even about your husbands future too know everything is in your hand just compromise and go back. May be there must be something good in your fold its God's will
